eZ8 CPU Instruction Classes
eZ8 CPU instructions can be divided functionally into the following groups:
• Arithmetic
• Bit Manipulation
• Block Transfer
• CPU Control
• Load
• Logical
• Program Control
• Rotate and Shift
Tables 128 through 135 contain the instructions belonging to each group and the number
of operands required for each instruction. Some instructions appear in more than one
table; these instructions can be considered to be a subset of more than one category.
Within these tables, the source operand is identified as src, the destination operand is dst
and a condition code is cc.
